At the same time, the sliding structure of the fixed frame 42 can reduce the situation of blocking the upper mold 14 during stamping, thereby improving the stability during use.

[0028] like Figure 1 and Figure 4 As shown, the side wall of the fixing frame 12 is fixedly connected to a liquid storage tank 5; the side wall of the fixing frame 12 is fixedly connected to a water pump 51; the liquid storage tank 5 and the water pump 51 are connected through a pipeline; the output end of the water pump 51 is connected to a second hose 53; the side wall of the sliding rod 43 is fixedly connected to a second fixing ring 52; the second hose 53 is fixed in the second fixing ring 52; the end of the second hose 53 is connected to an atomizing nozzle 54; when working, the sliding rod 43 is pushed to move to the lower die 11 before punching the material, which can drive the atomizing nozzle 54 to move to the lower die 11. When the atomizing nozzle 54 is pushed to move to the lower die 11, the atomizing nozzle 54 is connected to the lower die 11. When the nozzle 54 moves to above the lower mold 11, the water pump 51 is started to extract the lubricant from the liquid storage tank 5, and the lubricant is sent to the atomizing nozzle 54 through the second hose 53 and then sprayed into the lower mold 11. Through the above structure, the water pump 51 is set to connect the liquid storage tank 5 and the atomizing nozzle 54, and the lubricant can be sprayed into the lower mold 11 before the material is pressed to reduce the wear caused by the large friction between the material surface and the inner wall of the lower mold 11. At the same time, with the effect of the atomizing nozzle 54 on the diffusion of the lubricant, the contact between the lubricant and the lower mold 11 is more uniform, which improves the lubrication effect.

[0029] like Figure 2As shown, a guide head 6 is fixedly connected to the end of the positioning rod 21; the guide head 6 is arranged at the top position of the positioning rod 21; during operation, before the positioning rod 21 is inserted into the positioning hole 2, the positioning hole 2 will first contact the guide head 6. At this time, the arc-shaped structure of the guide head 6 can make the positioning hole 2 slide onto the positioning rod 21. Through the above structure, the guide head 6 is arranged to facilitate the alignment of the positioning hole 2 and the positioning rod 21, and to facilitate the correction of the position of the upper mold 14, thereby reducing the displacement of the position of the upper mold 14.

[0030] like Figure 1 As shown, a level 7 is fixedly connected to the side wall of the operating table 1; during operation, when the operating table 1 is tilted, the observation bubble in the level 7 will be offset, and the operating table 1 can be adjusted to a horizontal position. Through the above structure, the level 7 can be arranged to facilitate observation of whether the position of the operating table 1 is horizontal, so as to reduce the situation where a small tilt of the operating table 1 causes inconvenience in observation, thereby affecting the edge pressing effect of the material.

[0031] Working principle: When pressing the edge of the automobile material, put the material in the lower die 11. At this time, the bottom of the material will contact the top of the top block 17 in the lower die 11, and then start the hydraulic cylinder 13 to stretch it. At this time, the upper die 14 can move into the lower die 11. When the upper die 14 contacts the material and applies pressure, the material can move to the bottom of the lower die 11. When the material moves, it will press the top block 17 downward to move to the bottom of the first chute 15. When the top of the top block 17 is level with the bottom of the inner side of the lower die 11, the top block 17 stops moving. At this time, the first chute 15 will be in a contracted state. At this time, the upper die 14 will press the material on the inner bottom of the lower die 11 to complete the pressing edge, and then start the hydraulic cylinder 13 to contract and drive the upper die 14 to rise.

When the first slide groove 15 rebounds and drives the top block 17 to rise, the card block 19 will slide upward in the second slide groove 18, and will be limited and stuck when it moves to the top of the second slide groove 18. At this time, the top block 17 will stop moving. When the upper mold 14 moves into the lower mold 11, the positioning hole 2 on the upper mold 14 will contact the positioning rod 21 below. At this time, the positioning rod 21 can be inserted into the positioning hole 2 to correct the position of the upper mold 14, and then the upper mold 14 drives the positioning rod 21 and the connecting assembly to move downward to complete the edge pressing of the material in the lower mold 11. After the positioning rod 21 is inserted into the positioning hole 2, when the upper mold 14 continues to move downward, the connecting rod 31 will be The upper die 14 presses the positioning rod 21 and the connecting rod 31 to move downward at the same time, and then the upper die 14 performs the edge pressing process on the material. When the edge pressing is completed and the upper die 14 is away from the lower die 11, the second spring 32 rebounds and drives the connecting rod 31 and the positioning rod 21 to reset. Before the material is edge pressed, the sliding rod 43 is pushed to slide to the side of the lower die 11. At this time, the first fixing ring 44, the first hose 41 and the air outlet nozzle 45 can be driven to move to the side of the lower die 11. When the air outlet nozzle 45 is located above the lower die 11, the air pump 4 is started to drive the air flow into the first hose 41, and then blown from the air outlet nozzle 45 into the lower die 11 to blow away the metal debris and dust in the lower die 11, and then stop. The air blown by the air pump 4 then pulls the slide bar 43 to drive the air outlet nozzle 45 and the first hose 41 away from the lower die 11. Before punching the material, the slide bar 43 is pushed to move toward the lower die 11, which can drive the atomizing nozzle 54 to move to the lower die 11. When the atomizing nozzle 54 moves to the top of the lower die 11, the water pump 51 is started to extract the lubricant from the liquid storage tank 5, and the lubricant is sent into the atomizing nozzle 54 through the second hose 53 and then sprayed into the lower die 11. Before the positioning rod 21 is inserted into the positioning hole 2, the positioning hole 2 will first contact the guide head 6. At this time, the arc-shaped structure of the guide head 6 can make the positioning hole 2 slide onto the positioning rod 21. When the position of the operating table 1 is tilted, the observation bubble in the spirit level 7 will be offset. At this time, the operating table 1 can be adjusted to a horizontal position.
